RADIATOR.

Continuation of application Serial No. 340,601, filed November 25, 1919.This applicationfiled March 8,

To aZZ whom it may concern."

Be it known that I, Evnnn'rr B. CUSHMAN, a citizen of the United States,residing at Topeka, in the county or" Shawnee and State 01' Kansas, haveinvented certain new and usefui Improvements in Radiators; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains'to make and use the same, reference being had to theaccompany ing drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This inventionrelates to a radiator for internal combustion engines andone of the principal objects thereof is to lrovide a rotary radiatorhaving movement in response to the operating cycles of the engine sothat when the engine operates, the movement of the radiator will beinsured, the present application being a continuation of my applicationfiled November 25, 1919, Serial No. 840,601.

Another object of the invention is to provide an improved form ofradiator for maintaining the temperature of the engine within practicallimits and an important feature of the invention is to combine theradiator with a fly wheel so as to take advantage of the speed of thefly wheel for causing a circulation of the air around the liquidcontaining parts or tubes oi the radiator.

Still another object of the invention is to provide improved means forcirculating water through the radiator which consists of a stationarymember located in one of the rotary chambers of the wheel and tappingthe chamber at a point where the centrifugal pressure accumulates totake advantage of the diiierence in pressures between the two chambersof the wheel to move the water through the system.

While the invention is not necessarily limited to a portable stationaryengine, it is particularly applicable thereto because the radiator ismechanically driven through the air in such a manner as to causeeffective heat radiation and heat dissipation from the cooling liquid,even when the engine is standing still.

In those types of engine used for motor vehicles driven at relativelyhigh speeds and.

having air circulation superinduced by a fan driven from the engine, thepassage of air about-and through the grid or tubes of the radiator canbe more or lesssuccesstully accomplished butas is well. known,suchdevices become wholly inadequate whenthe motor car is standing still andthe engine Such devices as just described is running. are alsoimpractical for tractors or slow moving vehicles unless the radiatingsurface" a I is very large and the fan can move excessive volumes or airabout the radiator.

.The invention is so constructed that it may be installed with anordinary explosion motor without materially changing the construction ofthe motor and without the ne-p cessity" for supplying the tubeconnections and the excessive space for installations required byexisting types of devices for accomplishing the desired result.

Another advantage is that the entiredevice, including the engine andradiator can be supported from a single base so that 'a wheel, aportion'being broken away to show i the radiating device and air vane's,and

Referring now to the drawings showing the preferred embodiment of myinvention:

However, the collector unit including the water connectiondislr 30 and. and pipes and 50 are held against rotation by the anchorrod 54L one end of which engages the opening 55 in the water connectionto which it is fastened by the device 56 and the other end 01 i by thefasten struction.

Y has r:

In the illustrated embodiment of the inveution, the vanes or partitions2O 01": the fly wheel are provided with curved faces 18 so that when thefly wheel rapidly rewolves, air which issues through the spaces or ports15) at the perimeter of the'wheel is thrown out some distance from theperiphcry of the fly wheel, thereby permitting a free circulation of theair between the radiator rings and around the lit-tubes 4-1, throughwhich the water in the circulating system passes; When the fly wheel isrotating rapidly, the air is drawn into the center ot the fly wheel andthrown outwardly by centrifugal force but as it leaves. the periphery ofthe fly wheel it meets an inert body of the air which mightsubstantially check the velocity of the air issuing from the fly wheelunless some means 15 provided for throwing the air outwardly at somedistance.

Extensive experiments have demonstrated that the herein describedconstruction. is such that the air issuing from the fly wheel impingesagainst the curved, forward surfaces or the partitions 20 so that air isthrown a considerable distance and,

therefore, is not choked as it issues through the ports 19. Thus, treeunimpeded circulation o'l air is provided and on accountof therelatively large volume of air allowec to between the rings 40 andaround the tubes 41, heat from the water is quickly dissipated so thatrelatively cold water is returned to the cylinder.

In actual practice Iprefer to substantially fill the reservoir so thatthe entire system, including the fly wheel, tubes. and water jacket,completely full of water. For the best practice, the water lev l in thereservoir 6 should least be above the port. 8. Y

-i hen the parts are arranged and assembledas shown in Fig. l and theengine is started so that theily wheel revolves rapidly, water containedin the radiating unit carried around at a relatively high rate or:speed. The collector, consisting of the disks 30 and 45 and the vanes orblades 4:6 and 47, however, remains stationary due to its hich issecured to the port 8 device 57 of approved con connection through thecap 51, which is tied by the rod 54-. It will be seen that the flywheelis made up primarily of two water chambers, namely 33 and 35, which areconnected at their outer peripheries by the parent that when theflywheel is revolving,

each will be} subject to a centrifugal force whereby pressure willaccumulate in'each in proportion tothe speed at which the flywheel isrevolved. As pressure is greater on large diameters than on smalldiameters when the speed of revolution remains the same, it follows thatby inserting the collector 80 in the chamber 85, we have placed a partwhich is not subject. to centrifugal pressure at a point in the chamber35that is subject to considerable pressure. That this is a proven factis apparent when is considered that allthe flu d in the chamber 35,except that contained within theyCOl lector 30,'is subject tocentrifugal force" and inasmuch as this body of wa'ter is stationary, itis apparent. that thewater in chamber 35, which is subject tocentrifugalforce, will be caused to flow into the .001-

lector 30 under a pressure equal to the head,

or water oi. the same diameter as the cjol lector 3O'wh-1ch iscontamed'in the. chamber 33 because'the latter body, of water is subject tocentrifugal force and will cause an unbalanced condition in the twochambers. The remaining water in the chambers 33 and 35 which extendsoutwardly of the periphery of the Collector 30 will, of course, bebalanced according to the laws of hydrostatic pressure and if it werenotfor the collector 30 there would be no circulation whatever, but owingto the balanced condition 1t'1s apparent that the collector will meet noundue resistance fromzcentrii uga-l force otthe surplus water in theradiator because it acts under a perfectly balanced condition regardlessof the volume in, the

two chambers; I i

In tracing the circulation. of water through the system it will be notedthat water in the jacket 3 of the engine will be heated from theexplosions of gas and flow out of port 5 into the reservoir 6, passingdownwardly through the port 8, hose connection 10 through the port 275;,passage 5O,v

and openings 53 into the water chamber 33 of the flywheel where it isrevolved rapidly with the flywheel and is subject tocentrilugal force.The action of the collector in the chamber 35 then causes the water tobe drawn from the cha-mber83 through the- U- tul es all where the heatis radiated from the plates having central openings to provide inletsfor the air, Water circulating tubes extending transversely through saidplates, a Water chamber, and an impeller in the chamber for directingthe flow of water through the Water tubes.
